The small Wi-Fi Eye-Temp device monitors temperature and time on any item (stove, candle, iron, etc.) that is paired through one of their devices and connected to their mobile app. They say it's the first smart device that can monitor ANY item individually. You'll receive an alert when an item is left on for too long. This is specific to the item being monitored. When you set up Eyetemp, you will choose the type of item you are monitoring when you pair the device. If a rapid and drastic temperature change is noted, there is an alert that will be sent to notify you. This will note a potentially dangerous situation. When setting up the app you will have the option to add up to 3 emergency contacts. If you are non responsive to an alert, after a designated time period, the app will send a text notification to your emergency contacts. If you leave your residence while an item being monitored is considered in use, you will receive an alert. For example, if you leave while your stove is left on and it is being monitored by Eyetemp, you will receive an alert to remind you that the stove is in use. An optional feature is the Call Center. They will be notified after all of the emergency contacts are utilized and the problem remains. Eye-temp units are $29.99 each, and the app, iOS or Android is free.
